Let me be clear, rice is a safe and healthy food, it is one of the most commonly consumed starchy carb sources in the world with billions eating it around the globe. However, recent batches of the nutritious grain may contain higher than safe levels of carcinogenic metals such as cadmium and arsenic. Many foods that grow in the earth contain arsenic, but it is generally in very small amounts, but it turns out that a Greenpeace agency in Asia found harmful levels of cadmium in 12 of 13 rice crops tested. Although the levels are deemed low enough not to cause an immediate health concern, the levels are higher than recommended all the same. So in order to reduce the risk of contaminants, consider rice grown in African countries such as Egypt, Ghana, and Tanzania. You might also wish to consider rice from India, Pakistan or Nepal, these have all shown lower levels of said metals.
